Brexit: How Will UK Agriculture Fare?

There is little doubt that Brexit would have significant implications for UK agriculture, a sector with strong trade links to the EU and strong reliance on CAP income support. This article reports preliminary results from employing a Computable General Equilibrium Model, a Partial Equilibrium Model and Farm Level Models to explore selected trade and domestic policy scenarios post‐Brexit. These allow for the estimation of changes in producer prices, production and farm incomes against a baseline scenario of continued EU membership. Under a Free Trade Agreement with the EU, agricultural impacts are relatively modest. By contrast, unilateral removal of import tariffs has significant negative impacts on prices, production and incomes. Adoption of the EU's WTO tariff schedule for all imports favours net importers (e.g. dairy) and harms net exporters (e.g. sheep). Given the strong dependence of most UK farms on direct payments, their removal worsens negative impacts of new trade arrangements and offsets positive impacts. Impacts vary across different types and sizes of farm, but also regionally. However, the period of adjustment to new trade and domestic policy conditions may prove very challenging for a large number of farm businesses.     

Combining choice modelling and multi-criteria analysis for technology diffusion: An application to the uptake of electric vehicles

Efforts to reduce greenhouse gas emissions in the residential sector by adopting technologies such as solar photovoltaics and electric vehicles (EVs) have major implications for the capacity of electricity distribution networks, particularly at local areas with high uptake. Consumer decisions to purchase these technologies are also influenced by several complex criteria such as costs/benefits, performance, appeal/status, risk, psychographics, and demographics. This complexity motivated the development of an innovative diffusion model, incorporating features of multi-criteria analysis and choice modelling, to estimate the adoption of these technology options spatially across the landscape of heterogeneous consumers. We test the model to forecast market share of EVs through to 2030, using the vehicle stock across all 1.5 million households in Victoria, Australia. Seven financial and non-financial criteria were included and calibrated via focus groups and a large‐scale survey. Annual change of criteria values and their elasticity to adoption were incorporated. Geographical differences in uptake of EVs were primarily due to driving distance, employment status and household income, with urban areas having about three times the proportional uptake. By testing the model for a range of incentives, we demonstrate its capability to inform and evaluate policy options.     

Aggregate profitability and income distribution in the UK corporate sector, 1963–1985

This paper analyses the secular and cyclical behaviour of the rate of profit for the UK corporate sector from 1962 to 1985, using the growth accounting framework developed by Weisskopf (1979) for the USA, and the labour share decomposition of Henley (1987). The results show that the five per cent per annum decline in net profit rate in the UK over the period is explained in part by each of the three factors of declining profit share, declining capital productivity and, to a lesser extent, declining capacity utilization. As in the USA profitability peaks prematurely in each business cycle as a result of distributional pressure. Further decomposition of these components points to the importance of inadequate growth of real labour productivity as an explanatory factor, and to the inability of firms to protect profit share from the effect of the pre-1979 growing employer labour tax burden. The post-1980 profit revival in the UK is not explained by a ‘breakthrough’ in terms of an improved growth rate of labour or capital productivity but rather by the sheer length of the sustained business upswing and, as yet, absence of the usual midcycle upward pressure on labour share.     

THE DISTRIBUTION OF INCOME AND WEALTH IN JAPAN

This paper reviews research on the distribution of income and wealth in Japan, identifies sources of data on income and wealth, and describes limitations of these data. Evidence that Japan's poorest income groups are relatively well-off is convincing, but there is less evidence that the overall distribution of income in Japan is more equal than in other OECD countries. Agricultural policy, social welfare policy, the tax system, trends in earnings differentials, and the role of the Japanese family are among the many factors that have shaped Japan's income distribution. The rapid appreciation of the stock market and land prices during the late 1980s led to greater inequality in the distribution of wealth. Rapid population aging is expected to lead to an increase in total national wealth relative to national income which may have an adverse impact on the distribution of income.     

AIDing contraception: HIV and recent trends in abortion

Using a difference-in-differences estimation framework and state-level data, we investigate the potential role of HIV/AIDS in contributing to declining abortion utilization in the United States. Our results suggest that the perceived risk of HIV contraction negatively affected unwanted pregnancies. Specifically, a 10% increase in HIV incidence is associated with 0.34–1.1% fewer abortions per live births, an effect that can account for at least one-tenth of the sharp decline in abortions observed from the early 1980s to mid-1990s.     

Economic Analysis for the UK National Ecosystem Assessment: Synthesis and Scenario Valuation of Changes in Ecosystem Services

We combine natural science modelling and valuation techniques to present economic analyses of a variety of land use change scenarios generated for the UK National Ecosystem Assessment. Specifically, the agricultural, greenhouse gas, recreational and urban greenspace impacts of the envisioned land use changes are valued. Particular attention is given to the incorporation of spatial variation in the natural environment and to addressing issues such as biodiversity impacts where reliable values are not available. Results show that the incorporation of ecosystem services and their values within analyses can substantially change decisions.     

ALTERNATIVE MEASURES OF THE AVERAGE DURATION OF UNEMPLOYMENT

Four alternative measures of the average duration of unemployment are examined with the intention of illustrating: (1) the biases inherent in the average incomplete duration of unemployment, a statistic that is often the only one reported by many statistical agencies; and (2) the robustness of the average complete duration of unemployment to a host of assumptions underlying its derivation by non-parametric methods. Canadian data are employed, but the results offer a guide to the construction of the average complete duration of unemployment that may have broader applications.     

A financial planning model for presidential candidates

The necessity of entering a sequence of interrelated state primaries has forced presidential candidates to be much more deliberate in planning campaign finances. This paper presents a linear programming model for optimal allocation of time and money to each primary in order to maximize the number of delegates won. The model attempts to quantify and exploit the relationships between performance in early primaries and performance in later primaries, which has heretofore been labeled the “snowball effect.” Finally, the model, whose major use would be in overall strategic planning, is illustrated with an example.     

Where have all the traditional classroom settings gone?—The use of large scale, public sector projects to illustrate a multidisciplinary approach to problem solving

This work describes the evolution and potential of an elective course for students who have already been exposed to the standard techniques of problem solving as presented in traditional courses. Students apply these techniques to large scale problems in directed mullidisciplinary project teams. In doing so, they are provided with a unique learning experience allowing them to serve as a resource to the community. Course projects described here include the promotion of a railing retail district; the formulation, implementation and monitoring of litter reduction strategies; the economic evaluation of using inmate labor to clean public areas; and economic comparisons of recycling strategies for used tires.
